Material Characteristics of Plastic Deformation in High-Strength Steel
Keywords:
high-strength low-alloy steel, proof stress, strain hardening exponent, fractographic analysis, transcrystalline ductile failureAbstract
The paper is concerned with material characteristics of plastic deformation, relating to the occurrence and development of plastic deformation, proof stress and strain hardening exponent with changing testing temperature, in high-strength low-alloy steels. The material characteristics of plastic deformation were measured experimentally by means of a tensile test in the temperature range from –80 °C to +100 °C; subsequently, a fractographic analysis of fracture surfaces was carried out in order to evaluate failure mechanisms of the steels studied.
